16x^3+16x^2-25x-25=0

Lösung

16 x^{3} + 16 x^{2} - 25 x - 25 = 0

Lösung

x = - 1, x = - \frac{5}{4}, x = \frac{5}{4}

+1

Dezimale

x = - 1, x = - 1.25, x = 1.25

Schritte zur Lösung

16 x^{3} + 16 x^{2} - 25 x - 25 = 0

Faktorisiere

16 x^{3} + 16 x^{2} - 25 x - 25 : (x + 1) (4 x + 5) (4 x - 5)

(x + 1) (4 x + 5) (4 x - 5) = 0

Anwendung des Nullfaktorprinzips: Wenn

ab = 0

dann

a = 0

oder

b = 0

x + 1 = 0 or 4 x + 5 = 0 or 4 x - 5 = 0

Löse

x + 1 = 0 : x = - 1

Löse

4 x + 5 = 0 : x = - \frac{5}{4}

Löse

4 x - 5 = 0 : x = \frac{5}{4}

Die Lösungen sind

x = - 1, x = - \frac{5}{4}, x = \frac{5}{4}
